We experimentally study Bose-Einstein Condensates in optical
lattices as a promising candidate for scalable quantum information processing.
We study the superfluid-to-Mott-insulator transition as a means of initializing
a quantum register of singly occupied lattice sites. Interesting condensed
matter phenomena of the Mott insulator in 1-dimension have been explored
through transport measurements. We are beginning experiments to assess the
fidelity of the Mott state through spectroscopic measurements. Single q-bit
operations can be realized using a 3-photon stimulated Raman coupling field.
Also underway are experiments to realize 2-qubit operations in a 3D lattice of
double-well potentials, where the strength of the barrier is tunable in
real-time.
